ROLLER-BEARING FOR .No. 830,985. Specification of Application filed .J'anuary 10,

T (LZZ zqhom, it may concern:

Be it known that I, VVILLIAM T. FLEMING,

a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and Stateof California, have invented new and useful Improvements in Roller-Bearings for the Ends of Shafts, of which the following is a specification. My invention relates to a roller-bearing for a vcrtically-mounted shaft or to take the end thrust of a horizontally mounted shaft; and the object thereof is to reduce the friction on the shaft and hearing. I accomplish this object by the bearing described herein and illustrated in the accompanying drawings, in w nch Figure 1 is a plan of the facing-plate which is secured to the end of the shaft, (notshown) which plate is partly broken away, and of a part of a key in the keyway of said plate, and of the bearing-rollers and retaining-frame of the rollers, a part of the retaining-frame beg broken away for clearness of illustration Fig. 2 is a section on theline 2 2 of Fig. l with a portion of the shaft shown.

In the drawings, 3 is the base-plate, which is preferably hollow in the center. The upper and outer portion of the surface of this plate slopes downwardly and provides a run way for the bearing-rollers 4-, which rest thereon and are supported thereby. At each end of the bearing-rollers are grooves 5, which straddle tracks 6, preferably formed integral with the base plate. Spacing-rollers? are provided intermediate the bearingrollers. These spacing-rollers are provided with grooves S at each end of the roller, which are not as deep as the grooves in the bearing-rollers, and the spacing-rollers rest upon and are supported by the tracks 6 within these grooves. The spacing-rollers are enough smaller than the bearing-rollers so that they do not touch the base-plate neither do they touch the facing-plate 9, which is secured upon the end of shaft 10 by key 11, said key being received in the keyway 12 in the shaft and a keyway 13 in the facing-plate. This facing-plate rests upon and is supported by the bearing-rollers, and the under surface 1 or surface .vhichcontacts with the bearing rollers slopes upwardly and outwardly at the same angle that the THE ENDS OF SHAFTS.

tacts with the bearing-rollers. The baseplate is preferably circular and has secured thereto an annular ring \VhlClLPlOJGCt-S up- 4 of the bearing-rollers, as best shown in Fig. 2. To the top of this annular ring is secured an annular rim 15, which projects over the reduced outer ends of the rollers. duced outer end of each of thebearing-rollers is a chamber 16, in which is received a ball 17, which bears against the annular ring 14 and takes the end thrust of the bearing-rollers, it beingunderstood that the grooves in tle wider than the tracks which they straddle. The inner ends 4" of the bearing-rollers are likewise reduced in size,and near these reduced ends and secured to the base-plate is an annular ring 18, to which issecured an annular rim 19, which rim projects over the end of the rollers and with the rim over the outer end keeps the rollers in place when it is desired to handle the base-plate and rollers as a unitary body. The outer and inner ends of the spacing-rollers are likewise reduced and project under the rims 15 and 19, which hold them from separation when the base-plate and rollers are handled.

If desired, facing-plate 9 could be omitted and the end of the shaft turned to fit the bearing-rollers but as the wear comes at this point I prefer to make a facingpla,te which can be easily renewed when worn out. The center of the base-plate is preferably hollow, so that it may be slippedupon a stud in the foundation (not shown) to keep the baseplate in place. The pitch of the bearingro-llers is governed by the size of the shaftto be supported, taken together with the number of rollers to be used.

By this construction a very hezwy shaft may be provided with the hearing, which refriction thereon to the minimum.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A hearing for the end of a shaft co1nprising a base-plate having two upwardlyprojecting concentric annular tracks on'the upper face thereof, said upper face sloping baseplate slopes downward y and outwardly where the same con -downwardly and mitwardly; tapered bear- 1ng-rollers having grooves near the ends wardly to just above the reduced outer ends In the re-' quires no lubrication and which reduces the the outer ends of the bearing-rollers are a lit a ing-rollers,

than the bearing-rollersand having grooves thereof, said grooves being deeper than the height of. the tracks on the base-plate and receiving said tracks in' said grooves; and tapered spacing-rollersintermediate said bearsaid, spacing-rollers being smaller near the ends thereof" in which are received the tracks of the base-plate, said tracks supporting said spacing-rollers at and within said grooves.

2. A bearing prising a circular base-plate having two u f'wardlyeprojecting concentric annular trac v: onf'the upper face thereof, said upper face sloping downwardly nular ring surrounding said base-plate and' secured thereto; tapered bearing rollershavdug reduced ends and having grooves near the and outwardly; an anprising a circular base-platehaving two upwardly-projecting concentric annular tracks on the upper face thereof, said upper face sloping downwardly and outwardly; an an' nular ring surrounding said-base-plate and secured'thereto; an annular rim secured. to said ring and projecting inwardly therefrom; :tapered bearing-rollers having reduced ends and having grooves near the ends thereof,

said grooves being deeper than the height of the tracks on" the base-plate and receiving said tracks in said grooves; a'chamber in the outer end of each of said bearing-rollers; balls in said chambers; tapered spacing-rollers having reduced ends intermediate said for the end of a shaft com- 'slgpingdownwardly and outwardly; n
